Gravityfield2SphericalHarmonicsVector

This program evaluates a time variable gravityfield at a given time and saves a vector with the coefficients of a spherical harmonics expansion in the sequence given by numbering. If set the expansion is limited in the range between minDegree and maxDegree inclusively. The coefficients are related to the reference radius R and the Earth gravitational constant GM.

This coefficients vector can be used as a approximate solution, see NormalsMultiplyAdd, or as pseudo oberservations for regularization, see normalEquation:regularization.

For back transformation use Gravityfield2PotentialCoefficients with gravityfield:fromParametrization.
